In this paper, capacitive micromachined ultrasonic transducers are fabricated using a sacrificial surface micromachining process. A testing procedure has been established in order to measure the absolute transmit and receive sensitivity spectra of the fabricated devices. The experiments are performed in oil. Pulse-echo experiments are performed and the results are compared to the pitch-catch measurements using calibrated transducers. © 2007 IEEE.

Radiation impedance of an array of circular capacitive micromachined ultrasonic transducers in collapsed state Ozgurluk, A.; Atalar, A.; Koymen, H.; Olcum, S. (IEEE, 2011)Radiation impedance is one of the important parameters in designing efficient and wideband capacitive micro-machined ultrasonic transducer (CMUT) arrays. It determines how much acoustical power is generated in the surrounding ...
